Implementing Cisco Application Centric Infrastructure (DCACI) — Question 33

What happens to the traffic flow when the Cisco ACI fabric has a stale endpoint entry for the destination endpoint?

Answer options

• A. The leaf switch does not learn the source endpoint through data plane learning.
• B. The leaf switch drops the traffic that is destined to the endpoint.
• C. The leaf switch floods the traffic to the endpoint throughout the fabric.
• D. The leaf switch sends the traffic to the wrong destination leaf.

Correct answer: D

Explanation

The correct answer is D because when there is a stale endpoint entry, the leaf switch may direct traffic to the wrong leaf where the endpoint was previously located. Option A is incorrect as the switch can still learn the source. Option B is wrong since the switch does not drop the traffic; it simply misdirects it. Option C is not accurate as flooding is not the typical behavior in this scenario.
